During the last week Chandra completed the observing schedule as
planned.

Chandra passed through the nineteenth, twentieth, and twenty-first
eclipses of the season on Sep 22, 25, and 27 respectively, with
nominal power and thermal performance.

A real-time procedure was executed on Sep 27 to update the on-board
ephemeris.

A Chandra press release was issued on Sep 24 as a NASA press release
describing Chandra observations that have provided evidence that our
Milky Way Galaxy is embedded in an enormous halo of hot gas that
extends for hundreds of thousands of light years. The mass of the halo
is estimated to be comparable to the mass of all the stars in the
Milky Way galaxy. If the size and mass of this gas halo is confirmed,
it could be the solution to the "missing-baryon" problem for the
Galaxy. For details see:

Also of note this week was the Chandra Quarterly Review conducted on
Sep 25 in Cambridge.

The schedule of targets for the next week is shown below and includes
an observation of MAXI J0556-332, which is a follow-up to a Target of
Opportunity accepted on May 8, observations of the Orion Nebula
Cluster and SDSS J140829.26+562823.5 coordinated with the EVLA, and an
observation of Sgr A* coordinated with NuSTAR, Keck, VLT, SMA, CSO,
CARMA, ALMA, EHT, HESS, and ATCA.
